“…Data in Table 4 show clearly that there were no significant differences between the two seasons (S) for days to heading as well as seasons x genotypes (SxG) interaction. These results were similar to those obtained by Jackson et al (1994), Kosowska (1995), Oscarsson et al (1998) and Afiah et al (1999).…”

A field experiment was carried out in the Experimental Research Station at Nubaria, ARC representing newly reclaimed areas during two successive seasons of 2005/06 and 2006/07 to evaluate 16 barley (Hordeum vulgare L.) genotypes grown under water stress and calcareous soil conditions. The evaluation included yield and its components, growth attributes, earliness and kernel protein content. A randomized complete block design was used with three replications. Only two irrigations, i.e. at sowing and heading were applied to expose plants to water stress. Results showed that there are significant differences among the 16 barley genotypes for most of the characteristics.Four barley genotypes; Malouk//Aths/Linee686,Alanda-02/4/Arizona5908, Alanda/3/CI08887/CI05761//Lignee640, and Alanda/ Harma//Alanda01out yielded the check cultivars in grain and biological yield with some other advantages such as earliness, harvest index, leaf area index, and higher protein content. It is suggested that those genotypes could have more genetic stability studies to be grown in such calcareous soils.

“…In line with these results, many studies carried out across Mediterranean environments have reported positive associations between NKM and YIELD (Abeledo et al 2002;Acevedo et al 2002;García del Moral et al 2002Royo et al 2007), while the TKW component was found to be more variable in its contribution to the final yield levels as, for example, seen in barley and wheat (Martiniello et al 1987;Abeledo et al 2002;García del Moral et al 2002;Royo et al 2007;Moragues et al 2006a). This suggests that pre-anthesis conditions might have been essential to achieve high grain yields, while the post anthesis conditions did not necessarly favoured one component or another (Motzo et al 2001;Jackson et al 1994). This is also supported by the absence of compensation between Significance level: ns not significant, P [ 0.05; * P B 0.05; ** P B 0.01; *** P B 0.001 2 The significance of the genotype effect was tested against the interaction effect because the environments were considered as a random sample of the Mediterranean environment the environment means of NKM and TKW (r = -0.03, P = 0.960, n = 6).…”

“…Additionally, the phenology (later booting and maturity stages) of these genotypes, even if not strongly correlated to GEI as other covariables, may have been important for the specific adaptation to these environment conditions (Voltas et al 1999b;), possibly allowing a higher level of biomass accumulation at anthesis. The pre-anthesis climatic variables, namely the warmer temperatures from the vegetative stage to the early spike growth stage and the precipitations from the booting stage to the beginning of the grain filling period, may have favoured the high yield potential of VARs leading to a high number of kernels per m 2 and a high number of kernel per spike (Jackson et al 1994;Motzo et al 2001). …”

“…Moreover, they stressed that the low rainfall prior to the grain filling period affected the source/sink balance. Additionally, Jackson et al (1994) have shown that the rainfall level during the 2 weeks prior to anthesis is related to the amount of variation in grain yield potential of barley lines, both in rainfed and irrigated environments (under favourable moisture conditions). Similar results were also reported by Motzo et al (2001), working on spring triticale.…”

Genotype by environment interactions in barley (Hordeum vulgare L.): different responses of landraces, recombinant inbred lines and varieties to Mediterranean environment

Genotype-by-environment interactions (GEIs) can affect breeding progress because they often complicate the evaluation and selection of superior genotypes. This drawback can be reduced by gaining insights into GEI processes and genotype adaptation. Here, we have studied the GEIs over a set of 24 barley genotypes that were grown across six environments (location-by-year combinations) in Sardinia, Italy. Three groups of genotypes were analysed: barley landraces (LANs), recombinant inbred lines (RILs), and commercial varieties (VARs). The additive main effects and multiplicative interaction (AMMI) model was used for data analysis, and results evidenced no significant differences in grain yield averages for the 24 genotypes. However, there was a relevant GEI for yield mainly between two of the six environments (one characterised by warm pre-anthesis period and high spring rainfalls, and the other characterised by opposite features) and two groups of genotypes (VAR and LAN). Moreover, a negative trade-off between yield levels of genotypes was seen when the barley genotypes were grown in the contrasting environments. Overall, intermediate GEI levels were seen for RILs in comparison to LANs and VARs, and some of the RILs provided valuable yield levels (e.g. RILs 23 and 52). The results thus show the potential usefulness of LANs as a genetic resource for breeding, e.g. to obtain genotypes adapted to Mediterranean environments, such as the RILs analysed in this study.

“…Un des points les plus contestés est que l'index environnemental, constitué par les moyennes de l'ensemble des variétés dans chacun des lieux, n'est pas indépendant des données étudiées, ce qui peut introduire un biais dans l'estimation des paramètres de la régression (Freeman, 1973 ;Crossa, 1990 ;Gauch, 1992 (Freeman, 1973 ;Lin et al, 1986 ;Westcott, 1986 ;Becker et Crossa, 1990 ;Gauch, 1992 (1992,1996 , le blé (Crossa et al, 1991 ;Nachit et al, 1992a, b), le colza (Shafii et al, 1992), l'orge , le maïs (Cornelius, 1993) et le haricot sec (Saindon et Schaalje, 1993 (Freeman et Perkins, 1971 ;Rameau et Denis, 1992) ou par une ou plusieurs variables du milieu (Jones, 1979 ;Nor et Cady, 1979 ;Beckett, 1982 ;Kang et Gorman, 1989 ;Gorman et al, 1989).
